United States Patent RADIATOR RAISING AND TRANSPORTING JACKS Lewis C.Van Hnben, Orangeburg, N. Y.

Application August 5, 1955, Serial No. 526,692

2 Claims. (Cl. 214 650) My invention relates to improvements in jacks ofthe type adapted for using inpairs at opposite ends of steam or hotwater radiators for transporting purposes.

The primary object of my invention is to provide a telescopicallyextensible and contract-able jack for the above purposes having levermeans for extending the same with a minimum of effort by an operator andmeans for locking the lever to lock the jack extended.

Another object is to provide in such a jack easily applied fasteners forattaching the jack at the end of high or low radiators.

Still another object is to provide a jack having the above advantagesand which is simple in construction and strong, while light in weight,and comparatively inexpensive to manufacture and safe to use.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 1 is a view in side elevation of a pair of my improved jacksattached to a radiator and extended;

Figure 2 is an enlarged view in front elevation of one of the jackscontracted and partly broken away and shown in section;

Figure 3 is a view in vertical section taken on the line 3-3 of Figure2;

Figure 4 is a similar view showing the jack contracted;

Figure 5 is an enlarged, fragmentary exploded view in side elevation ofparts of one of the fasteners;

Figure 6 is an enlarged view in perspective of means for attaching thefasteners to the jack; and

Figure 7 is an enlarged fragmentary view in horizontal section taken onthe line 7-7 of Figure 4.

Referring to the drawings by numerals, 1 designates a radiator having apair of my improved jacks 3, 5 applied thereto at the ends thereof. Thejacks 3, 5 being duplicates with the exception presently noted, adescription of one will sufiice for both.

The jack 3 comprises a wheeled frame 4 of inverted U-shape having a pairof tubular standards 7 connected together adjacent lower ends thereofside by side and parallel by a tubular cross member 9. The standards '7and member 9 are formed of standard piping and welding, not shown,connect the standards 7 to member 9. Horizontal foot plates 11 aresuitably secured to the lower ends of the standards 7 and are supportedby wheel forks 13 having small wheels 15 mounted therein. The footplates 11 and wheel forks 13 are offset outwardly and to one side of thestandards 7 for stabilizing purposes and bracing gusset plates 16connect the standards 7 at the outer sides thereof to the foot platesand are suitably secured thereto. The wheels 15 of the jack 3 are castorwheels for steering purposes, whereas, the wheels of the jack 5 run inplanes transverse to the plane of the jack 5 preferably.

2,784,860 Patented Mar. 12, 1957 A jacking frame 17 vertically slidableon the wheeled frame 4 comprises a pair of elongated tubular slides 19of piping slidably fitted on the standards '7 and connected together byan upper cross cleat 21, a. lower cross cleat 23 and a central crosscleat 25, each suitably attached to said slides 19 as by welding 27. Thecleats 21, 23, 25 are at the front of the jack 3 and extend outwardlybeyond the slides 19 and are provided outwardly of said slides withvertical slots 29 therein for a purpose presently seen. The ends of thelower cleat 23 are twisted forwardly, the purpose of which willpresently appear.

A pair of fasteners 31, 33 are provided for attaching the jacking frame17 to one end of the radiator 1 with the cleats 21, 23, 25 facing saidend. The fasteners 31, 33 each comprise a short link chain 35 forengaging a selected link at one end in the slot 29 in one end of one of.the cleats 21,23, 25 and having a bolt 37 with a washer 39 and wing nut41 on its other end for attaching in the slot 29 in the other end of thecleat and tightening the chain. A similar pair of fasteners 32, 34 isprovided for the jack 5.

Lever means is provided for raising the jacking frame 17 to extend thejack 3 comprising a hand lever 43 in the rear of the jack and which ispivoted above the jacking frame 17 for vertical rocking movementtransversely of the jack on a cross shaft 45 retained by end nuts 47 ina pair of lateral rearwardly extending ears 49 on the standards 7.Bushings 51 on the shaft 45 between the ears 49 and opposite sides ofthe lever 43 act to center said lever relative to said jack. The lever43 is provided with a short lever arm 53 operatively connected to thejacking frame 17. The operating connection comprises a pair of links 55depending from opposite sides of the lever arm 53 and pivoted at upperends thereto, as at 57, with lower ends pivoted, as at 59, to a lateralrear lug 61 on the upper cleat 21.

Referring now to the operation, the jacking frame 17 normally slidesdownwardly on thestandards 7 onto the member 9 by gravity to contractthe jack 3, as shown in Figures 2 and 3, thereby pivoting the lever 43into upswung position. To extend the jack 3, the lever 43 is swungdownwardly against the lug 61 parallel with the jacking frame 17 as bestshown in Figure 4. This causes the short lever arm 53 to swing upwardlyto lift the links 55 and hence the jacking frame 17 on the standards 7.

The locking means for the lever comprises a locking pin 63 attached by achain 65 to the lug 61, a pin receiving hole 67 in the lever 43 on theopposite side of the shaft 45 from the pivot 57, and a pair of oppositepin receiving holes 69 in the links 55. When the lever 43 engages thelug 61 which thereby establishes the down swung position of said leverand the extended position of the jack, the hole 67 aligns with the holes69 and the locking pin is inserted through said holes to lock the lever43 down and to the links 55 all as best shown in Figures 5 and 7.

The pair of jacks 3, 5 are applied to the opposite ends of the radiator1 while contracted, and against said ends and facing the same in thefollowing manner. The pair of fasteners 31, 33 for the jack 3 areattached to the ends of the upper and lower cleats 21, 23 in the manneralready described with the upper fastener 31 looped through the upperportion of the radiator adjacent one end thereof and the lower fastener33 looped around the lower end of one coil adjacent said end. Thefasteners 32, 34 for the jack 5 are similarly applied to the jack 5 andto the radiator 1.

If the radiator 1 is of the low type, the upper fasteners 31, 32 areapplied to the intermediate cleats. After the fasteners 31, 33, 32, 34are applied the jacks are extended in the manner described to lift theradiator 1 at 3 opposite ends thereof for transporting on the jacks ifdesired.

The foregoing is considered as illustrative only of the principles ofthe invention, Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

1. A jack for lifting a radiator comprising an inverted U-shapedframeincluding a pair of vertical standards, a cross member connecting thelower edge thereof, a jacking frame vertically slidable on saidstandards and normally resting on said cross member, a lever for liftingsaid jacking frame, means pivotally mounting said lever on said U-shapedframe above said jacking frame for downward swinging to lift the jackingframe, means operatively connecting the lever to the jacking frame,cross cleats on the jacking frame, and flexible fasteners adapted to belooped around coils of the radiator and attachable to said cleats forsecuring said lifting frame to the radiator, said second named meanscomprising a pair of opposite links pivoted at one end to said lever,and a lug on one of said cleats to which the other ends of said cleatsare pivoted, and locking means for said lever, comprising a locking pin,said lever and links having apertures therein aligned in the downswungposition of said lever for insertion of said pin therethrough.

2. The combination of claim 1, said lug limiting downward swinging ofsaid lever to align said apertures.
